Question $2$: Analyse the indeterminate truss shown. The support at $\backslash (\backslash$mathbf$\{$A$\}\backslash )$ is pinned. The support at $\backslash (\backslash$mathbf$\{$C$\}\backslash )$ is horizontal roller. The support at $\backslash ($ D $\backslash )$ is vertical roller. Use the Force Method to find the following:

a$)$ State whether the truss is externally or internally indeterminate and by what degree?

b$)$ Determine the reaction forces $\backslash (($F$)\backslash )$ of the supports

c$)$ Detemine the axial forces in each member and state whether they are in compression or tension

d$)$ Also apply the compatibility check

Note! For Area $($A$)$ of every member and Modulus of Elasticity $($E$),$ please check the figure Consider reaction at $\backslash ($ D $\backslash )$ as Redundant.
